PROBLEM TO BE SOLVED: To provide composite materials of nano-dispersed silicon and tin and methods of making the same.SOLUTION: Methods of making composite compounds include oxidation of alloys, reaction of stabilized lithium metal powder with tin oxide and silicon oxide, and reaction of inorganic salts of lithium with tin- and silicon-containing compounds. Composite compounds of tin and lithium, silicon and lithium, or tin, silicon, and lithium having tin and silicon nano-dispersed in a lithium-containing matrix may be used as electrode materials and particularly anode materials for use with rechargeable batteries. |
